The beastly roar of the Nine-Tails echoed through the sealed space. Completely enraged, it rampaged wildly on the sealing altar, venting its fury. The rattling sound of the sealing chains filled the air as endless negative chakra spread outward, dyeing the entire sealing space crimson.
That damned brat actually used genjutsu to simulate dozens of Madaras! And these Madaras were just as proud and unruly as the real one.
There was no mindless roaring or hysterical cursing—just a cold, indifferent tone and a condescending gaze, as if they were merely lecturing an ant out of sheer boredom.
There were no particularly vulgar or dirty words, yet every sentence was so venomous that it made the Nine-Tails want to tear them apart!
This kind of genjutsu instantly dragged it back to the days when it was at Madara's mercy. Even after breaking free from the illusion, it still hated Madara far more than it hated Kei.
"You should be grateful to Madara, brat!" The Nine-Tails spoke in a chilling tone, its sharp teeth grinding audibly.
A suffocating aura of killing intent, resentment, and hatred enveloped Kei, as if the beast would tear him apart at any moment.
Kei grinned, completely unfazed by the oppressive emotions. He even had enough presence of mind to protect Kushina as well.
Thanks to the enhancement of [Transmigrator], his mental power was far beyond that of an ordinary person.
If this were the real world, being enveloped by such murderous intent and malice might cause some stress reactions in his body. But only his spiritual form had entered the sealing space. The negative emotions released by the Nine-Tails had no effect on him.
The Nine-Tails stared at Kei for a long moment before letting out a scornful chuckle.
The overwhelming killing intent and rage gradually subsided.
Even though the genjutsu Kei had used was just a low-level technique, the sheer strength of his mental power gave the Nine-Tails a sense of oppression comparable to the Eternal Mangekyō Sharingan.
In nearly a thousand years of existence, there were only a handful of people who had ever given it such pressure.
If it truly lost control and went berserk, considering its current sealed state... Who the hell knew if this brat would turn into another Madara?
How could he have such terrifying mental strength without a Sharingan? How had he trained his Yin Release genjutsu to such a level?
Damn it! Sage of Six Paths, you better explain this to me! The Nine-Tails cursed in its mind, but it couldn't win in a fight, and it couldn't out-insult the brat either.
What else could it do?
"Teach me~ teach me~" Kushina grabbed Kei's arm, her big eyes filled with anticipation and admiration.
After spending so many years with the Nine-Tails, she could immediately tell—this arrogant, unreasonable, and insufferable fox had actually backed down!
"Ahem... I don't think that's really necessary..."
Kei coughed dryly, struggling to imagine Kushina spouting curses. After all, disrupting the Nine-Tails' mind had already given him enough existential satisfaction.
If he ended up corrupting Kushina too... That would be a crime!
Besides, when they eventually became an old married couple, this would probably come back to bite him...
Teach her how to curse? Maybe just a little.
"Just teach me~ You don't want me getting bullied by this stupid fox every day, do you?"
Kushina clung to Kei's arm, dragging out her words in a pleading tone. As she spoke, she discreetly traced the word "scare" in his palm.
"... Alright, fine. How about I tell you all about its secret origins and history?" Kei pretended to look troubled but agreed.
He wasn't stupid. The moment he felt Kushina writing in his palm, he realized—she just wanted to scare the Nine-Tails. To make it rein itself in a little and stop running its mouth so recklessly.
"Mm-hmm! Mm-hmm!" Kushina nodded eagerly, like a pecking chick.
Knowing the Nine-Tails' secrets? That was a brilliant idea!
Even if she never actually used this information, just having it would give her leverage.
"If you dare tell her, don't even dream of me getting along with her peacefully!" The Nine-Tails' fur bristled as its blood-red slit pupils locked onto Kei.
If it were anyone else talking about its lineage, it would simply sneer.
After all, events from a thousand years ago had long been distorted by fragmented historical accounts, making it impossible for anyone to truly know the truth. No matter how people speculated, they could never guess what really happened.
But this little bastard—he actually knew!
During that genjutsu earlier, the first thing that broke its composure was, of course, Madara.
The second was that everything Kei said through Madara's mouth was logical and well-founded, leaving the Nine-Tails no room to refute it.
"We're just going over your family tree—why are you so worked up?" Kushina put her hands on her hips, looking triumphant as she watched the Nine-Tails struggle to even come up with a proper threat.
Now she truly understood the power of knowing someone's lineage! You might never actually use it, but you had to have it.
See? Just mentioning it had already made the fox blow up!
The Nine-Tails gritted its teeth and glared at Kei and Kushina.
"Give me a smile, and I won't listen to him." Kushina grinned mischievously, deliberately making her request sound playful.
Anyway, her boyfriend knew all about this stuff. She could just ask him again once they left the sealing space.
The Nine-Tails nearly shattered its own teeth from grinding them, cursing all the way from Ashina to Kushina, covering every single member of the Uzumaki clan it could think of.
As for those ancestors even further back? They were so distant that Kushina wouldn't even recognize their names—what was the point in cursing them?
"Let's get down to business first."
Kei patted Kushina's hand, stopping her from further provoking the already enraged fox. Though he did enjoy watching a thousand-year-old fox get bullied, there were more important matters at hand.
"Oh, okay." Kushina wasn't sure what the "business" was, but she obediently stopped teasing the Nine-Tails.
"Kurama, does your summoning contract with Madara still exist?"
The moment Kei spoke, not only the Nine-Tails but even Kushina's pupils shrank.
Tailed beasts could form summoning contracts?!
"And what if it does?! That bastard is already dead!"
"First, Madara may be old, but he's not dead yet. Second, even if he does die, he'll definitely leave behind a successor and won't let go of a powerful asset like you. Third, Edo Tensei."
"... That self-righteous Senju! Why invent such a technique!! Such an idiot!" The Nine-Tails cursed bitterly.
Even if it didn't believe Madara was still alive, the second and third possibilities were real threats. Especially the third one! That damned Tobirama! Even in death, he was still causing it trouble!
Serves him right for getting killed by Kinkaku and Ginkaku.
"How about I help you with a Contract Seal?"
Kei smirked. Seeing how the Nine-Tails was venting all its frustration on cursing Tobirama, he knew the tsundere fox had already accepted his judgment.
"Hah! Let her do it—you don't have enough chakra." The Nine-Tails scoffed, glancing at Kei with disdain.
A Contract Seal required a sealing formula strong enough to completely suppress the connection between the summoner and the summoned entity.
With its massive size, did he really think his chakra reserves were enough? Hah!
